SDKs

Hi there,I am new to using RevenueCat with Capacitor and I'm encountering an issue during initialization. I attempted to configure RevenueCat using Purchases.configure within my application code, but the process returns an error code of -1. Could you please advise on what might be causing this issue and how I can resolve it?Thank you for your assistance!

I'm using custom fonts in my iOS app. They're provided via a Design System Swift Package and registered programmatically using `CTFontManagerRegisterFontsForURL`: private static func registerFonts() { guard let fontURLs = Bundle.module.urls(forResourcesWithExtension: "ttf", subdirectory: nil) else { return } for url in fontURLs { var error: Unmanaged<CFError>? let success = CTFontManagerRegisterFontsForURL( url as CFURL, .process, &error ) // ... error handling }}The fonts are registered at app launch before Revenue Cat Paywall is displayed. However, when the Paywall tries to use these fonts, the SDK appears to not detect that they're already registered and attempts to download them from the Revenue Cat CDN, resulting in this error:GSFont: "NewSp

Hello! Could I please get some guidance on a code change for my app to address a crash that appears to be tied to some code from a RevenueCat sample project? I have a shortcut that launches my iOS app and then navigates to a View. I realized that there is a crash scenario. If I initially run the shortcut from the Shortcuts app when the app wasn’t running it correctly launches the app and navigates to the View. However, if I then go back to the Shortcuts app and run the shortcut again the system correctly switches to the app but then the app crashes. To investigate I ran the app in debug mode and was quite surprised to see where it was crashing. It was inside of my tip jar, which I haven’t changed the core logic for since I first developed my app in 2023. I used the Magic Weather SwiftUI sample project as a basis for the consumable, in-app purchases in my tip jar. Here’s the code that was causing the issue:

Looking into the REST API v1 and v2 and what the web sdk does, I’ve noticed that https://api.revenuecat.com/rcbilling/v1/subscribers/<user_id>/products?id=<product_id> is kind of what we need. Is it safe to use? I don’t see any documentation around.Thanks! 

We use AppsFlyer for attribution and RevenueCat for subscriptions. I am referring to this article: We currently call Purchases.collectDeviceIdentifiers(); again after the user has given ATT consent.What is not clear to me though: Do we have to collect IDFA consent before signup and before showing the paywall / any purchase happening? Or does that not matter?Thanks

I get the error 'SubscriptionPeriod' is ambiguous for type lookup in this context. during a ReactNative iOS build in DraftBit since version 9.7 of react-native-purchases. I reverted to 9.6.15 and the error disappeared. The error appeared in this line:static func rc_normalized(subscriptionPeriod: SubscriptionPeriod) -> StringIs there something I can do to fix this?

I’ve been getting warnings about an old unused offering which does not let me delete.How can I get rid of these warnings?The sometimes hang the simulator / emulator tests ( not on real device ).I can not seem to delete this offering even though they are deleted from the app store.If I can delete it from the app store, revenuecat should let me delete it as well. Am I wrong?What am I missing? 

I understand RevenueCat doesn’t support Windows and Linux for Flutter for now. I’m new to RevenueCat, so I want to know whether there are any workarounds to allow users pay when they are using Windows or Linux. For example, directing to web? If it’s possible, how?

Good Evening, I have been working with Revenue cat’s flutter SDK, this is my code:  var configuration = PurchasesConfiguration('goog_**********');configuration.entitlementVerificationMode = EntitlementVerificationMode.informational;await Purchases.configure(configuration); After configuring the SDK, I think it fetches the products automatically which I don’t want. I have only one product (infinity) which is a non-consumable product. However what I see in logs:I/[Purchases] - INFO( 3470): ℹ️ Missing productDetails: UnfetchedProduct{productId='infinity', productType='subs', statusCode=3}I/[Purchases] - INFO( 3470): ℹ️ Product not found: infinity - Product Type: subs, Reason: PRODUCT_NOT_FOUND, Serialized doc ID:  I dont have any subscription product, yet it fetches a subs type product and could not find it.What is the solution for this error? Or am I making some mist

Anyone know’s how to resolve this?  SDK is not ready?

Hello,I have a working subscription system with revenuecat for a jazz education app. I wanted to be able sell individual lessons. I heard from many customer that they would want individual lesson purchases that is unlocked for life. I have 42 lessons in the app now and I plan to add more. It will be around 150-180 lessons total. So, What is the best practice here? Do I need to create 150 SKUs ?I have 6 categories and that number will be 10 categories soon.Every lesson in each category will have the same price. However, I will need to track who bought which lesson? So could I somehow have 10 categorical prices to simplify things down and still track 150 lessons with it? Thanks..

Our paywall on iOS works perfectly fine right now. It fetches the products/offerings and displays the paywall UI.However on Android we are only showing the offerings and not the paywall UI. Was curious if anyone knows the solution/problem?We are running RC:react-native-purchases - 9.7.0react-native-purchases-ui - 9.7.0expo: ^54.0.19We are displaying the paywall via: <RevenueCatUI.Paywall>

I current offer subscriptions through the App Store, Google Play, RC Web Billing, and Stripe directly.I’m investigating implementing the Customer Center and see that it fully supports managing App Store & Play Store subscriptions and promo offers for win backs but it’s not clear to me if it supports management of subs from RC Web Billing and Stripe.My specific questions are:If a customer has a RC Web Billing sub: Can they cancel/manage it from the Customer Center? Do they still have to re-auth from the email magic link? Can I configure win back promo offers? If a customer has a subscription through Stripe directly, can they manage it from the Customer Center, ideally by linking to the Stripe Customer Portal? I’m fine without promo offers on Stripe but it is important that my existing Stripe subscribers ca

In my flutter app on Android, paywall is not showing for one user, with endless loading. I have not received any other reports on this problem. The user is detected as from Russia, which might be an issue, but Google seems to support that for subscriptions, at least there is a price. I don’t see any exceptions (there is an analytics event supposed to be thrown if revenue cat paywall fails), so I guess it is just freezing forever SDK version 9.8.0video:https://drive.google.com/file/d/1v5rkR5kP6tsm22T4iCYIN3SbAdHzpScA/view?usp=sharing

We can honour entitlements that were purchased on other platforms by calling login(appUserId).What if someone purchases a package on ios, then logs out of the app, then creates a new appUserId.Wouldn’t this create a scenario where multiple appUserId’s have an entitlement from a single purchase?

We want to use the remote paywalls in our app and as there is no problem with iOS we encountered layout issues on bigger screens (e.g. iPad).Is there a way to define a safe area for the paywall? We’re not presenting it as a sheet since we need to embed in the parent view that swaps the views based on the state.If it’s not possible to have a safe area defined the only way of doing so is to change the sizes to fit and set paddings so that the view is hugging the actual size?What we’d like to achieve looks something like this what was mentioned in this post: 

Hello RevenueCat Support Team,We are integrating RevenueCat Web SDK (@revenuecat/purchases-js) with Stripe Checkout for our web subscription flow.We are passing customerEmail during purchase, like this: await Purchases.configure(WEB_BILLING_PUBLIC_API_KEY, appUserId); await Purchases.getSharedInstance().purchase({ rcPackage: selectedPackage, customerEmail: subscriptionData?.email, }); Expected behavior: Email field should be hidden or pre-filled for all users (since we already pass customerEmail). Current behavior: For most users, the email field is hidden / pre-filled, which is correct. For some users (e.g., kavita@flunzy.ai, kruti@flunzy.ai), the email field still appears on the subscription screen. We understand that Stripe Checkout controls whether the email fiel

Im extremely stuck on submitting my app to the app store.I tried to submit my app to the app store - but it got rejected based on the paywall screen erroring.Im using a custom screen. I have a few questions.Do I have to submit the app and the subscriptions together?Surely this leads to a catch 22 - where the paywall screen will not ever serve the subscriptions since they are still in review…Ive been waiting for my subscriptions to get reviewed now for like 4 days - I’m wondering if i need to submit the whole APP again for review - to get them to review the whole app again and therefore review the subscriptions (?).If I use my prod revenue cat key - i get a similar error appearing…@app/mobile:dev:  WARN  [RevenueCat] ⚠️ RevenueCat SDK is config

I’ve seen these two threads:  and  And the blog post announcing the availability of paywall support for (non-flutter) web sdk here: https://www.revenuecat.com/blog/company/paywalls-on-the-web/ It would be very helpful to know if you have specific plans to add paywalls for web to the flutter SDK, and if so what the timeline might look like, so I can figure out whether I need to roll my own ahead of time or wait for a supported version.

Is it possible to log in users anonymously?Currently we are facing an issue. We user Firebase in our apps and in order to send notifications we need to store push tokens in our database. So, we sign in users anonymously to Firebase, and then we can store this info under their user ID.The problem arises when we then call Revenuecat’s login function. We do this so that if a user contact’s us we can match them between Firebase ID abd Revenuecat.However, the problem arises in that now Revenuecat treats the user as signed in. So, same user trying to access the app on two devices will not be able to do so, as the purchase is constantly transferred from one user to the other.Hence a question - is there a way to provide anonymous alias? So that we can search users by their firebase id, but tell Revenuecat “this one is not signed in, so apply anonymous behavior to purchases transfers”.Alternatively, this could be sorted by allowing us to search customer by

Hi everyone,we are using RevenueCat’s new paywall UI feature in Unity on iOS. To present different paywalls under different conditions, we take use of the custom attribute system and the targeting feature. This works well except a once triggered paywall only changes after restarting the app. In other words, there is always the same paywall presented (using PaywallsPresenter.Present) even when the conditions for the targeting rules changes. A change is only applied after restarting the app. So it is impossible to show one paywall and then show a different paywall (i.e. with reduced prices) afterwards in one session. Again, this only works if we completely close and restart the app in between.Is there a way to manually refresh the paywall? Or can I somehow invalidate the cache?Thanks in advance!

Hello,Currently, the Customer Center only supports plan changes on iOS and doesn't seem to offer this functionality on Android.Is this something that is planned or possible? Since we already have subscription groups configured, could we potentially implement this using pure Flutter code by leveraging the official API?The tool is great, but having to use the Customer Center for iOS while maintaining a separate custom page for Android plan changes is difficult to justify and explain to our end-users.Thank you in advance for your help!

I am setting up two tiers of subscription “Plus” and “Pro” I have followed threads from other posts on the forums such as: iOS its 1 Subscription group, with 2 service levels Android its 2 separate subscriptions RevenueCat its 2 separate entitlementsUsers are successfully able to purchase either tier with thisI am now trying to figure out how best to handle allowing a user to upgrade their entitlement from plus to pro in react-nativeThe issue with presenting the paywall again is that the user sees the same tier they already have (plus), which seems confusing and I wouldn’t want them to re-pay for the same subscriptionIs it possible to re-use the existing paywall I use for upgrading to either plus or pro hiding the plus option condi
